The documentary details the history of the TCE contamination from the Behr Dayton Thermal Plant in the the McCook Field neighborhood in Dayton, OH.

In today’s news, residents are asking EPA for new widespread testing of indoor air in the neighborhood to rule out risks of exposure by vapor intrusion. So far, EPA has not agreed to the testing. In what appears to be yet another dubious, knee-jerk, party-line denial from federal agencies, Stacey Coburn, the U.S. EPA’s project manager for the site, has stated that “she doesn’t believe anyone’s health is at risk from the plume” despite reports of nearby groundwater contamination levels exceeding 900ppb of TCE and previous confirmation that dangerous levels of TCE have already poisoned indoor air in certain homes.

Meantime, a lawsuit has been filed on behalf of the contaminated community who apparently disagree with EPA’s empty reassurances.

Drinking water supplies for tens of thousands of people near three active Superfund sites in the Bountiful and Woods Cross areas have been at risk or even polluted because of groundwater contamination.

The pollution is so bad that the federal government decided to join state regulators in directing long-term cleanup efforts [...] No related posts.]]> The Deseret Morning News (UT) reports:

Drinking water supplies for tens of thousands of people near three active Superfund sites in the Bountiful and Woods Cross areas have been at risk or even polluted because of groundwater contamination.

The pollution is so bad that the federal government decided to join state regulators in directing long-term cleanup efforts of those sites.

Business owners who bought property in the affected areas, but were unaware that sources of contamination within the Superfund sites were beneath them, are expected to pay for removal of tainted soil and old polluting underground tanks that were put in long before they came along. Federal funds for cleanup are available for Superfund sites if they are active on the Environmental Protection Agency’s National Priorities List, but some property owners still pay.

Utah Division of Drinking Water director Ken Bousfield said last week that water suppliers in Bountiful and Woods Cross are, based on the most recent tests, providing clean drinking water. Bousfield also is aware of the plumes of contaminated groundwater in those areas and how test results can change.

“That’s why you monitor,” he said.

The EPA lists at least 14 active Superfund sites in Utah that are among the worst hazardous waste sites in the country. Two sites in the Woods Cross and Bountiful areas are active due to three plumes of groundwater polluted by chemicals used in the past by dry cleaners, automotive garages and other industry.

A third Superfund project on the EPA’s active National Priorities List is called the Intermountain Waste Oil Refinery site, located in Bountiful in the area of 995 South and 500 West. That site, listed in 2000 as a federal priority, has been deemed by the EPA as “under control” in terms of risk for human exposure to the chemical pollutants.

At one time, however, the Utah Department of Environmental Quality and EPA were looking into whether those who rely on the so-called East Shore aquifer for drinking water — about 68,000 people — were “potentially affected” by a release of dichloroethylene into the aquifer.

Woods Cross public works director Scott Anderson follows state and federal testing regulations, which call for sampling of two wells every three years. He said municipal drinking water in his city is safe, serving about 7,400 people.

“Safe as anywhere else in the country,” Anderson said. “I think it’s very safe.”

Still, Woods Cross shut down one of its four drinking water sources, which supplied half the city, due to contamination by tetrachloroethylene, which the EPA said consistently was above the Cancer Risk Screening Concentration. Karla Scott can see the well from her home, where someone representing Woods Cross showed up about five years ago asking to test her water.

“He said it was OK,” Scott said. “You just go on with your life and don’t worry about it.”

If she wanted to, Scott could take a water sample for testing to the Utah State Health Lab, which sometimes takes special individual cases on, or to the private Chemtech-Ford Laboratories in Murray. The state lab does rigorous testing for water utilities throughout Utah.

Anderson said a test in 2004 showed that one of the three remaining active wells in Woods Cross turned up traces of trichloroethylene (TCE), but not at a level unacceptable by federal standards.

Bousfield said that in a few past isolated cases elsewhere in Utah, contamination has been so bad in drinking water supplies that people could actually smell chemicals in the water. When that happens, he added, there is a potential for an immediate health risk.

“It’s such a rare occurrence,” he said, unable to come up with a specific example over the phone. “I’m sure they do exist.”

5th South Plume

One of two large plumes of polluted groundwater in the Bountiful and Woods Cross areas, defining one Superfund site, is bad enough that seven of 26 domestic wells in the affected area are believed to have been contaminated by chemicals at concentrations that exceed acceptable federal levels. The potentially cancer-causing chemicals connected to that site are perchloroethylene (PCE) and TCE.

The EPA calls those two plumes the Bountiful/Woods Cross 5th South PCE Superfund Site, a place the EPA has assessed as “Human Exposure Not Under Control.” Mario Robles, the EPA’s project manager over the 5th South site, federally listed as a priority in 2001, said last week that cleanup of those plumes migrating under about 450 acres could take about 15 years.

“Really, nobody knows — it could be more, it could be less,” Robles said on the phone regarding a remediation time line.

So far, the plume contaminated with PCE has made its way into two residential drinking water wells, with one homeowner accepting the EPA’s offer of being hooked up to municipal water without charge. The other homeowner, Robles said, is opting to rely on filters for clean drinking water, preferring its taste over city supplies.

“The issue is if they change it often enough,” Robles said about the filter. “We explained the risks to them.”

The remaining five of the seven affected domestic wells are used primarily for irrigation, and Robles said there is not a risk of human exposure to the polluted groundwater around those wells. State regulators don’t keep track of water quality in private wells.

The two plumes, located roughly in the area of 500 South and 800 West in Bountiful, are slowly moving west, and the area of impact could spread, increasing the potential for future exposure from ingesting contaminated groundwater or by inhaling vapors as people use the groundwater for irrigation, according to the EPA.

Robles said that as soon as next month the EPA will decide whether soil near the Bountiful Family Cleaners, in operation since the 1940s but under different ownership, is contaminated enough with PCE to warrant removal and replacing. If that happens, the current owners of the cleaning business may have to cover some of those costs. PCE has been a preferred chemical used by dry cleaners for decades, dating from long before more strict disposal standards for PCE were put in place.

Ronald Bangerter bought the business in the 1960s and now owns it with his eight sons. One son, Bryce, said he hopes Bountiful Family Cleaners won’t have to pay any more than the $100,000-plus it already has spent during the past six years on legal fees and to look for pollution under the property.

“Sleepless nights, gut-wrenching, worried, what’s going to happen to the business,” is how Bryce Bangerter describes those six years. “We’ve run a clean ship since the ’60s.”

Prior to Bangerter’s family owning the business, waste went into a septic tank that drained into a field. But it’s unknown, Bangerter said, if the tank is still underground.

Until cleanup of the two 5th South plumes begins, the EPA is checking eight monitoring wells around the 400-acre PCE plume and 13 monitoring wells around the 50-acre TCE plume to watch how and where they move. The EPA believes the TCE plume has not impacted any wells.

The EPA’s plans for cleanup of the two plumes includes drawing the groundwater out, cleaning it and putting it back into the ground. Another method being considered involves adding nutrients into the polluted groundwater to speed up a natural degradation process.

Five Points Plume

A second Superfund site in the area, which is known by the EPA as the Five Points PCE plume, is a third plume of contaminated groundwater. It is located in the area of approximately 1500 South and State Highway 106, and received its active Superfund priority listing just last year.

The EPA’s on-scene coordinator, Duc Nguyen, said Your Valet Dry Cleaners owner Jim Patterson paid just under $100,000 last year to remove 43 cubic yards of contaminated soil and an old 1,000-gallon underground tank that Patterson said was leaking “bad gasoline.” The irony is not lost on Patterson that he had to pay for removal of a contamination source that wasn’t even linked to the dry cleaning industry.

“We pretty much feel confident that we removed the source of contamination,” Nguyen said.

Excavation stopped, however, partly because of so many underground utility lines and the area’s proximity to busy streets. And Woods Cross shut down one of its four drinking water wells because of consistently high amounts of potentially cancer-causing chemicals showing up in tests. The EPA said that migration of the plume is likely to increase contamination in wells over time.

Nguyen added that the EPA does not yet know the size of the Five Points plume west of Patterson’s business, located just up the hill from Karla Scott’s home of 40 years. Although there is one old monitoring well a block away, and the EPA will be installing new monitoring wells in the coming year, at this point it’s unknown what the impacts are from that plume, which the EPA said contains PCE.

Patterson recalled two other dry cleaners near the old Five Points Mall that possibly could be held accountable for the Five Points plume, but he said they are no longer in business. Patterson bought his Bountiful location in 1963. The money he spent on testing and clean-up is not covered by insurance, although the expenses do qualify as a tax write-off.

“You don’t get much of a sympathetic ear, because you own the land, and who owns the land pays,” Patterson said. “If I could go back on who had the tank, I might seek recovery from them.”

Even though the Five Points plume got its official EPA priority listing last year, Patterson has been dealing with state and federal officials for about nine years, drilling and testing to see where and what type of contamination existed. It is all a result of a drinking water test years ago that found unacceptable levels of PCE present.

Your Valet now says on its Web site it is the first dry cleaner in Utah to offer a new process called GreenEarth Cleaning, which instead of PCE uses a silicone-based cleaning solution developed by General Electric in the 1990s. It is a modified liquid silicone similar to what’s found in cosmetics, shaving creams and deodorants that “will not pollute our water, soil or air.”

Patterson said only one of his six locations still needs converting to GreenEarth, at a cost of about $15,000. There’s no law that says he has to make the conversion, but it’s something he said he’s doing in good conscience.

“There’s not a lot more that I can do, short of tearing up the intersection and knocking the building down,” he said. “It’s expensive, and we’ve done what we can do. I hope it’s over.”

The Aberdeen Contaminated Ground Water site in Aberdeen, North Carolina has been proposed for addition to EPA’s National Priorities List (NPL) of hazardous waste sites. It is one of six hazardous waste sites to be proposed for addition to the NPL, while twelve sites nationally are being added to the list.

The Aberdeen Contaminated Ground Water site is about 1 acre in size and located on highway Route 211 in Aberdeen, Moore County, N.C. Powdered Metal Products (PMP) manufactured precision machine parts at the facility from 1980 until 1995. The operation utilized a trichloroethene (TCE) dip-vat as part of the manufacturing process. During the investigation of ground water contamination at the Geigy Chemical Corporation NPL site in 1990, which is located just on the other side of State Route 211, TCE, lead and pesticide contamination was detected in numerous private wells along Crestline Lane and Route 211. Investigations have identified contaminated soils in the vicinity of the former TCE dip-vat utilized by PMP as the source of TCE contamination in the ground water.

In a follow-up article in The Fayettville Observer (NC), we learn:

Trichloroethene also was detected in the town’s municipal water supply wells No. 5 and No. 9, according to an EPA report [PDF]. The level of the chemical exceeded the federal Safe Drinking Water Act maximum contaminant level.

The report said the town took the wells offline for some time and is now blending water from those wells with water from other municipal wells to reduce the trichloroethene levels.

The EPA provided municipal water supplies to 56 residences and businesses in the area, according to the agency.

A dry-cleaning shop on busy U.S. 1 has been proposed as a federal Superfund site after tests found nearby soil and groundwater contaminated with hazardous chemicals.

An Environmental Protection Agency official said the site presents no immediate health risk, but Broward County’s pollution prevention chief said he isn’t so sure.

A dry-cleaning shop on busy U.S. 1 has been proposed as a federal Superfund site after tests found nearby soil and groundwater contaminated with hazardous chemicals.

An Environmental Protection Agency official said the site presents no immediate health risk, but Broward County’s pollution prevention chief said he isn’t so sure.

Flash Cleaners, at 4131 N. Federal Highway [map], polluted the ground with a variety of chemicals used in the dry-cleaning business, most likely through spills and disposal of waste through a septic system, according to the Environmental Protection Agency. Tests of soil and groundwater found concentrations of several chemicals exceeding federal safety standards, including dichloroethene, trichloroethene, tetrachloroethylene and vinyl chloride.

Although the shop still takes in dry cleaning, it no longer processes it on site.

Barbara Schuster, project manager for the EPA, said there’s no immediate danger to public health. Eight drinking-water wells, serving Hillsboro Beach and other portions of northern Broward County, are within a mile of the site. But Schuster said there is little danger to the wells because they lie northwest or southwest of the site and the groundwater flows east, away from the wells.

Jeff Halsey, Broward County’s director of pollution prevention and remediation, said there is not enough information to determine how much danger is posed by the underground spread of hazardous chemicals. Among the possible health effects of these chemicals are liver and kidney damage, neurological diseases and cancer, according to the federal Centers for Disease Control and Prevention.

“Until we can get an assessment done and know exactly where the plume is going, we’re going to be very, very concerned,” he said.

The exact cause of the contamination is unknown, although environmental inspectors documented unsafe practices at the shop, according to EPA records. They found machinery and waste containers on a bare concrete floor without secondary containment. Wastewater from the dry-cleaning work was discharged into an on-site septic tank, which caused contamination of soil and water, according to the EPA.

The Superfund program, established after the discovery of thousands of tons of hazardous waste in the Love Canal neighborhood of Niagara Falls, N.Y., takes on the most serious contaminated sites. Under the program, the EPA tries to find the parties responsible for the pollution and make them pay for cleanup. Failing that, the Superfund pays, although its funds have dwindled since the expiration of a special tax on industries that pollute.

The owners of the shop, John and Susan Ferrel, say they didn’t cause the contamination and can’t afford to pay for cleaning it up. They bought the store in 1977 after working there for a year, and they’ve worked there ever since. They said they disposed of the waste properly and have been forced to pay for a preliminary environmental study because a state inspector found a small amount of dry-cleaning chemicals at the bottom of an unused machine.

“Because of that one thing, we spent a lot of money over the years trying to do what the county wanted and what the EPA wanted,” Susan Ferrel said, speaking from their home in Sebastian. “We just can’t afford this. It will take all our retirement.”

The EPA will conduct a study of the site and figure out a cleanup plan. Among the most likely options are digging up the soil and taking it to a landfill or pumping up the water and treating it to remove the contaminants. It is unknown what will happen to the business.

The one-story, peach-colored shop stands just back from the noisy traffic of Federal Highway. An American flag hangs in the window. A sign in the door states that it is closed Monday. Behind the shop is the Beacon Heights neighborhood, consisting of small apartment buildings and one-story houses.

“This is the first I’ve heard of it,” said Bob Manko, standing on the porch of his house on Northeast 42 Street. “If there’s something bad there, it ought to be cleaned up.”

But he said he hoped a small business wouldn’t be harmed by having to spend an excessive amount, unless the cleanup is necessary.

“Common sense should prevail,” he said.

EPA owns a bad-ass mobile toxin detector. Officially, it’s known as the Trace Atmospheric Gas Analyzer (TAGA). According to EPA:

The Trace Atmospheric Gas Analyzer (TAGA) is a self-contained mobile laboratory capable of real-time sampling and analysis in the low parts per billion level of outdoor air or emissions from various environmental sources and concerns. In addition, the TAGA has specialized sampling equipment for measuring indoor air and at remote locations.

As we understand it, EPA has a limited supply of these mobile labs. Apparently, one of them is headed to Dover, DE this spring:

Federal pollution investigators will dispatch a mobile laboratory to Dover this spring as part of an expanded probe of toxic vapor risks from chemical contamination in groundwater flowing under the state’s capital.

The Environmental Protection Agency work will target pollutants spilled into the soil from a former coal gas plant and dry cleaning operation west of the city center.

Studies of the Dover Gas Light Company Superfund site have been under way since the mid-1980s. More than a decade later, officials acknowledged concern that vapors from some of the contaminants might trickle into buildings after escaping from shallow, tainted groundwater.

[...]

Part of the work scheduled for this spring includes use of a mobile Trace Atmospheric Gas Analyzer (TAGA) bus to sample vapors under the bottom slabs of buildings along the contamination plume.

The TAGA samples can be drawn from a small hole drilled into the floor of buildings, in a process that takes about 30 minutes. Some indoor air sampling work also is planned, using small, portable devices that collect samples over a 24-hour period.

[...]

Although public water supplies are considered safe from the pollution, past tests have found shallow groundwater contamination levels in worst-hit areas thousands of times higher than federal drinking water standards.

Chemicals most often mentioned include tetrachloroethylene (PCE) and trichloroethylene (TCE), solvents used in dry cleaning that are known to cause cancer or other health problems after long-term exposure at high levels.

Efforts to make homes safe from contaminated groundwater fumes near the Behr Dayton Thermal Products plant, 1600 Webster St., have run into problems at as many as 10 homes.

And the effort to clean indoor air contamination at a nearby school is ongoing, authorities have said.

TCE fumes have migrated from the soil into the homes, businesses and schools, creating potentially hazardous vapors.

In homes that have dirt basement floors, those floors must be sealed for the air evacuation systems to work properly, said Mark Case, director of environmental health for Public Health Dayton & Montgomery County.

Levels of contamination in the problematic homes have reportedly dropped below 10 ppb. That’s still 25 times the Ohio Department of Health’s exposure limit of .4 ppb.
